heap - How can you allocate a raw mutable pointer in stable Rust? -

i trying build naive implementation of custom string -like struct small string optimization. unions allowed in stable rust, came following code: struct large { capacity: usize, buffer: *mut u8, } struct small([u8; 16]); union container { large: large, small: small, } struct mystring { len: usize, container: container, } i can't seem find way how allocate *mut u8 . possible in stable rust? looks using alloc::heap work, available in nightly. if you'd allocate collection of u8 instead of single u8 , can create vec , convert constituent pieces, such calling as_mut_ptr : use std::mem; fn main() { let mut foo = vec![0; 1024]; // or vec::<u8>::with_capacity(1024); let ptr = foo.as_mut_ptr(); let cap = foo.capacity(); let len = foo.len(); mem::forget(foo); // avoid calling destructor! let foo_again = unsafe { vec::from_raw_parts(ptr, len, cap) }; // rebuild drop // *not* use `ptr` / `cap` / `len` anym...

elasticsearch - Logstash omitting daylight saving time when parsing date -

my log file contains timestamp without timezone indicator. in format dd-mmm-yyyy::hh:mm:ss my server located in central europe, in timezone utc+1 uses dst results in utc+2. a date in log file: 2017-07-25::17:30:00 parsed 2017-07-25t16:30:00z . should 2017-07-25t15:30:00z . in dst now. logstash seems consider timezone not dst. how can fix this? my logstash config: date { match => ["logdate", "dd-mmm-yyyy::hh:mm:ss"] target => "@timestamp" remove_field => "logdate" } you need specify timezone dates in: date { match => ["logdate", "dd-mmm-yyyy::hh:mm:ss"] target => "@timestamp" remove_field => "logdate" timezone => "europe/zurich" <-- add line } you may change "europe/zurich" whatever timezone makes sense you ( other list of time zones might of use )

Sharing code across Swift OpenWhisk actions -

i'm trying out openwhisk actions in swift. better or worse, of openwhisk documentation javascript. when writing actions in javascript, looks can package code npm module , require/import action. swift, there's no indication there's way share code. found 1 sample project ( https://github.com/swiftontheserver/drinkchooser inestimable @rob-allen) uses clever trick of pre-processing source code files before building them: cat actions/_common.swift actions/myaction.swift > build/myaction.swift is there official way share code across actions? many thanks. building swift binaries locally , creating actions binaries allow this. swift's package manager generate multiple executables if have correct directory layout. this example project uses serverless framework build , deploy multiple binaries openwhisk actions. creating actions swift sources files not support providing multiple sources files code sharing.

python - Why is try-finally valid, but not try-else-finally? -

i found python throwing syntaxerror @ me trying try without except : try: spam() else: eggs() finally: semprini() instead, forced write: try: spam() except: raise else: eggs() finally: semprini() which felt silly, want eggs() executed before semprini() — if put contents of else: -clause after finally: -clause executed after semprini() . although there has been try without except proposal in past, semantics different there implication except: pass , i.e. polar opposite of i'm after. interestingly, try: without either except: or else: is valid , can't have else: if don't have except: . although there may different way formulate same, alternatives i've thought of (probably) have subtly different behaviour. why presence of else: require presence of except: ? you should have written try: spam() eggs() finally: semprini() in absence of except clauses, else useless.

javascript - How do make HTML page load after AngularJS gets response from database? -

i have table on html page data stored in database. want table or whole page loaded after data received. can this? angularjs code: angular.module("app", []).controller("controller", function($scope, $http) { $http({ method: 'post', url: 'updatecoins.php', data: {get: 1}, }).then(function(response){ $scope.db = response.data; }); }); the table gets filled this: <tr> <td>{{db[0]['percent']}}%</td> </tr> generally you'd use resolve router this. can this: angular.module("app", []).controller("controller", function($scope, $http) { $scope.dataloaded = false $http({ method: 'post', url: 'updatecoins.php', data: {get: 1}, }).then(function(response){ $scope.db = response.data; $scope.dataloaded = true }); }); then in html on outermost element load controller use ng-if="dataloaded"
